Stone Dust Is The Answer
Sand.well, if you use a really heavy sand you might get away with it. Most of the sands that are packaged for sale however are way too fine. You can use a course sand for under the flagstones, sure. Back when I used to lay brick patios I would use course sand or quarry screenings inter-changeably and it was fine. Them patios still look good. Those are brick patios however, where the space between the paving units is about a quarter inch wide. The problem with sand is that it washes away by action of water, blows away by action of wind, and gets carried away by action of ants. Thats why stone dust AKA screenings AKA decomposed granite works much better, for underneath flagstones, than sand.
Learn how-to use the stone dust as a leveling agent: the process is described HERE.
What Is The Best Material To Put Between Flagstone
Sand: Sand is the most common joint filler, but it is challenging to keep in place and needs to be refilled. Rocks: You can use small rocks to fill large gaps, and gravel or crushed rock can be used to fill smaller gaps. Mulch: Bark and lightweight chunks of mulch are a great option for in-between flagstone.

How To Install A Flagstone Paver Patio
Flagstones, bricks, or pavers make it possible for a backyard concrete patio to be more than a cold, gray slab. Select a location in your yard and sketch a basic plan. Before you break ground, contact your local utilities about locating any underground lines, pipes, or cables. Also decide which method you’d like to use to install your patio: sand or mortar. This piece covers both methods.
Prepare The Area And Lay Concrete
Once you have the all-clear from the utility company, you can start digging. Make sure that you dig your entire path about 5 inches deep. Once you have done this, you need to get the surface as level and compact as possible. Make sure that you flatten and even it out using a tamper.

Some homeowners prefer a somewhat random placement that more closely replicates how rocks lay in nature. On the other hand, some people like symmetry and patterns in their walkway. This design choice is entirely up to you.

What Kind Of Mortar Do You Use For Flagstone
- Do you know what mortar is? Its a combination of water, sand, and cement.
- You have to use the sand and cement in a ratio of 2:1 each. If you are taking sand in 2 cups, you have to make cement in 1 cup composition.
- Now start mixing in a container, pour water to make a consistency into the mixture, and continue pouring until it reaches the cake frosting-like consistency.
- If you are installing flagstones 1st time, its better to take all small quantities.
Do Cold Temperatures Slow The Chemical Hardening Reaction
As the air temperature drops so does the temperature of materials stored outdoors and the actual concrete to which the flagstone and brick will be attached. These cold temps radically affect the chemical reaction of hydration that starts the moment water is added to the powdered cement and hydrated lime.
Hydration is the reaction that turns the powdered cement and lime into actual microscopic cement paste crystals that interlock the sand particles together.

Flagstone Patios That Are Set In Sand Are Vulnerable To Ants And Wash
Occasionally Ive seen a paver patio messed up by ants. But with flagstone patios that are set in sand ants always attack. I suppose its because the joints are inevitably wider with flagstone and/or because the flagstones are varying in thickness meaning you end up with deeper sand in some places. Whatever the exact reason, I can tell you that all of the flagstone patios that I have seen that are set in sand eventually get run amok by ants.
Another reason to use screenings is because screenings also make an excellent joint filler.
You do not want to use sand, even course sand between your flagstone joints because it can wash awayunless of course your flagstones are absurdly tight. For pattern-cut flagstone, yes, you can maybe get away with using sand as the joint-filler. Just make sure the base is course sand, not fine. You will need to use fine sand for the joints however because of how tight they are. Again, ants love fine sandbut in this application, pattern-cut stones, tiny jointsfine sand will not be the end of the worldso long as the base is course, of course. Thats for pattern-cut flagstoneor any flagstone where the joints are super tightin those cases you can maybe get away with sand, so long as you follow the guidelines that Ive set earlier in this paragraph. For irregular flagstone, or any flagstone with a joint wider than a quarter of an inch, you really really should try and avoid sand, and instead use stone dust.

Puzzle Together The Flagstone
Start by grabbing the larger stones and placing them around the perimeter of the patio. You want to use the larger stones on the outside because smaller stones will move and shift with time. Large stones will lock the smaller stones toward the center in place.
Then, start adding the rest of the stones to the center, working toward the middle of the patio. Cutting the stones is time-consuming and dusty, so spend a few minutes trying to puzzle them together, so you have to make as few cuts as possible.
Heres a quick tip: The tighter and more consistent you try to make the seems, the longer its going to take because youll have to make waaaay more cuts. If you dont mind bigger gaps, youll save a ton of labor, and you can get by with fewer stones to save some cash.
To cut the stones, you can use anything with a diamond blade on it. You see me using an angle grinder in the video, but there is a much easier way to cut the stones, which is to use a concrete saw with a larger diamond blade, as I demonstrate here.

Can I use the masonry sand under the flagstone? And then the granite on top? Or is the masonry sand to pose-able? Like it will slip and move too much. I dont know what I can use the masonry sand for thats in the back of my pick up.
